Spacelog Apollo 8

Go ahead, Houston.

Okay, Apollo 8. We would like to update your LM state vector, CSM state vector, and target point. If it is convenient now, why, we will go ahead and do that if you will go to P00 and ACCEPT.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Okay. The loads are in and verified, and the computer is yours.

Okay.

You can take it back to BLOCK, and for Bill's information, latest guess from the main bus post-SEP voltage to 27.5

Guess! You mean the EECOM's are guessing?

At least, they are honest for a change.

That is more than you can say for the computers.

Apollo 8, Houston.

Apollo 8, Houston.

Go ahead, Houston. Apollo 8.

Okay, 8. We have an entry PAD for you.

Good. Just a minute.

Ready to copy, Houston.

Houston, Apollo 8. Entry PAD as follows: mid-Pacific, 357 152 359 146:29:30 268 plus 0813 minus 16503 065 36221 645 12122 36301 146:46:14 0028, next block not applicable, 400 0212 0025 0334 0814 16059 312, Zeta Persei, up 165, right 35 up, use nonexit EMS pattern, backup alignment; Sirius, Rigel, roll 308, pitch 209, yaw 357, and we won't need P65.

Okay, Apollo 8. I would like to verify sextant star shaft 0590, and the boresight star.

Roger.

The last one is right 34. Over.

Roger. Boresight star is right 34. And I have the sextant shaft; that's 0590.

Apollo 8, Houston.

Apollo 8, Apollo 8, Houston.

Go ahead, Houston.

Okay, Apollo 8. Can you tell us if you've done anything with your potable water? We've noticed our readout has gone from 100 percent down to 56 in the last couple of minutes.

We're reading about 50 percent right now.

Roger. That correlates with what we see. Have you done anything to change configuration? Over.

Yes, we noticed the venting here, too, Houston.

Jim, did you mean you could visually see it?

Yes, we're—oh, stand by, Ken. Bill just dumped urine, so that might have been urine we were seeing.

Bill just shut the potable inlet, Ken.

Houston, Apollo 8.

Go ahead, 8.

Apollo 8, Apollo 8, go ahead.

Roger, Houston. We're still showing about 52 percent, and we had our switch on waste so we don't know whether it dropped from a higher value or not. Has yours been stabilized now?

That's affirmative; ours has stabilized now. It was reading full just a few minutes ago.

Roger. I don't think—we can't account for any sudden drop in water.

Okay. We looked in the malfunction procedures, and number 28 doesn't reveal anything very startling.

Houston, Apollo 8. Over.

Go ahead, 8.

Okay. I'm looking at malfunction 28, and it takes you to box 6, but I don't really think that's the problem because the waste tank quantity hasn't changed any. Over.

Okay. I concur. We're watching the same thing.

Look, we don't care about the potable tank, but we do about the waste tank, so just in case there is a problem somewhere, I'm going to shut the potable tank off and leave the waste tank inlet valve open. How does that sound to you?

Apollo 8, Houston. Radio check.

Apollo 8, Apollo 8. Radio check.

Read you loud and clear.

Apollo 8, Houston.

Houston, Apollo 8. Did you call?

Apollo 8, Houston. You are loud and clear. We've taken a look at this water —

Houston, Apollo 8.

Apollo 8, Apollo 8, Houston. Read you loud and clear. We have taken a look at your potable water quantity problem, and it appears to be a transducer problem. Suggest that you leave the potable tank isolated. You have sufficient water in the waste tank to continue the entry. Over.

Roger. Thank you, Houston.

Does that mean we're GO for entry?

Houston, Apollo 8.

Apollo 8, Apollo 8, go ahead.

Houston, how do you read? Apollo 8.

Read you loud and clear, Apollo 8, and we're checking on the PTC problem now.

Apollo 8, Houston. You are cleared with entry attitude at this time.

Houston, Apollo 8. Over.

Apollo 8, loud and clear. Go.

Apollo 8, Apollo 8, go ahead.

Roger. We have completed the checklist down to the 1-hour point, and we'll stand by for 1 hour.

Roger.

Apollo 8, Apollo 8, Houston.

Go ahead, Houston.

Just for information, did you folks end up having to use any command module RCS heaters?

Negative. All our indicators are pegged either high or at 5 volt.

Okay. Thank you.

Carnarvon, network GOSS conference voice check. How do you read?

Network, Carnarvon. Read you weak but clear.

Roger, Carnarvon. I read you loud and clear.

You are loud and clear now. Thank you.

Apollo 8, Houston. Stand by for hand over to Carnarvon.

Apollo 8, Houston.

Go ahead.

Go ahead, Houston.

Okay, Apollo 8. If you will go to P00 and ACCEPT, we would like to update your LM and CSM state vectors. Over.

Apollo 8, Houston. State vector load is complete. Verify the computer is yours.

Apollo 8, Apollo 8, Houston. State vector load is complete; the computer is yours.

Roger, Houston. We are going to BLOCK.

Apollo 8, Houston.

Go ahead, Houston.

Okay. Two fast items: number one, it has been suggested that since Marezine takes some time to take effect, you might consider whether you would be interested in taking some now. And I have an entry PAD which has some very small updates to go on it if you would like to copy that.

Okay. Stand by. Let me get out the entry PAD.
